Gravitrax PRO Helix Element — Intersecting Track Stone for Up to Six Balls

The Gravitrax PRO Helix Element lets up to six tracks intersect: when a ball rolls into the helix it leaves at a lower level, allowing up to six balls to travel along the stone at the same time. Combine this PRO Element with any GraviTrax Starter Set to add multi-track interaction and fresh dynamics to your marble runs. Part of the flexible, expandable GraviTrax system for ages 8 and over.
